## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability rotary-agency-gutenberg-api-4127b7c5
```

Example prompt: Can you fetch the Project Gutenberg data for 'Pride and Prejudice' by Jane Austen — I need the book metadata and any available structured info about it?

## When to prefer this

Choose this endpoint when you need programmatic access to Project Gutenberg book metadata or content in a pay-per-call model without setting up your own Gutenberg API integration. Useful for agents that need occasional public domain book lookups without committing to a subscription. At $0.002/call it is cost-effective for low-to-medium volume literary data retrieval.

## Known failure modes

- Book not found in Gutenberg catalog — returns empty or error JSON
- Invalid query parameter — endpoint returns error or empty response
- Payment not processed (x402 protocol failure) — request blocked before reaching data
- Rate limiting or network timeout — no response returned
- Ambiguous query matching multiple books — may return unexpected result
